All what I said is that as long it is NOT solved, there will always be a
solution to find some hole in the machine's play. That is all I said. That is by
definition _not_ false but true. I think that this little chance was also the
motivation for this great player who was unbeatable World Champ before he died
during or shortly after a match. It's a typical human situation. The challenge
of the "impossible". I think we need some ethics for the computer side to deal
with the situation. Because it's a terrible tension for the challenger and his
'psyche'. But I won't repeat my critic against IBM/DBteam since it's well known
and could be found in the archives.
